FXBW Series Rod-Type Composite Suspension Insulator for 11–220kV Transmission Lines

Lightweight, Pollution-Resistant Solution for Overhead HV Networks

The FXBW series rod-type composite suspension insulator is a high-performance insulating device widely used in 11kV to 220kV overhead transmission systems. Featuring a silicone rubber housing and fiberglass rod core, this insulator offers superior mechanical strength, excellent hydrophobicity, and outstanding anti-pollution performance compared to traditional porcelain models.

Each unit conforms to IEC 61109 and GB/T 19519 standards, making it suitable for use in polluted, coastal, alpine, and high-altitude environments.
